Entropy seems like a chaotic chemical to me but not the opposite to Gravity.
1) Zanz has decreed 
the opposite of 
and 
the opposite of 
.
2) Nova is not chaotic but is entropic.
its not a chemical, because entropy is what i call a repetetive state of "disorder", therefore it has no physical property but rather influences other physical properties such as the molecular dissarrangement of a chemical.
Gravity on the other hand represents a form of "Order" and isn´t as spontaneous as Entropy since it has only a single state of equilibrium, therefore i concur that
is potentially the opposite of
.
From what ive learnt of this article : Entropy and disorder (
http://hyperphysics.phy-astr.gsu.edu/hbase/therm/entrop.html#e3), Entropy is "disorder" and to cause disorder, it needs "multiplicity". what it means by Multiplicity, is the amount of molecules that can be disarranged in a single space of matter. The greater the multiplicity, the greater the Disorder.
Randomness can be associated with "Information Entropy" which is an indicator of how much information a single event holds. The more information that single event has, the more uncertain or random the ending result of that event can be.
this can be related to multiplicity:
for example: you roll a pair of dies, and you aim for a 7.
there are three ways with which you can produce a 7, meanwhile there is only one way to produce a 2 or 3,
two ways to produce a 4 or 5, and three ways to produce a 6.
6 and 7 have the greatest multiplicity. therefore its more possible to produce either a 6 or 7.
and in total there are 12 possible outcomes, therefore that is the level of Randomness of the die.
